Quality Control

Our Ethynyl(Phenyl)Iodonium Tetrafluoroborate is manufactured under strict quality protocols to ensure batch-to-batch consistency and high reactivity. Each lot undergoes comprehensive analytical testing, including NMR, HPLC, and elemental analysis, to confirm identity, purity, and the absence of critical impurities. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from incompatible materials such as strong bases and reducing agents.
